Used with Motorola MC1505 AiD converter when making precise measurements of slowly varying DC voltages in digital voltmeters or in feedback controls.Closed-loop front-end buffer provides high input impedance and reduces stray noise and 60-Hz pickup. Two-pole filter is included in unity-feedback loop of buffer. Front-end scaling circuit is induded with buffer.—D. Aldridge and S.
